Windows 7 Virtual Router using netsh wlan set hostednetwork

The virtual router function in W7 is fantastic and I am running a small PAN now consisting of a media server with a WiFi card and connection to internet, and two laptops connected using WiFi to the server.

My question is about speed and radio type.

The server has a Ralink RT2860 chip which should and reports to support 802.11n

I WOULD LIKE TO FORCE REMOVE PASSWORD AND WI-FI Encryption off of the virtual wireless network is there some type of patch or hack i can do this for some reason Microsoft is forcing you to put a password on the network as if we're unable to think for ourselves and they know best.
